Building Cisco Service Provider Next-Generation Networks, Part 1 (SPNGN1)

Question No: 41 – (Topic 4)

Refer to the exhibit.

R1 and R2 are running RIPv1 for the 10.0.0.0 and 192.168.1.0 networks. No default or static routes have been configured on the routers. Which two statements about this topology are true? (Choose two.)

R1 summarizes the 10.1.1.0/24 subnet to 10.0.0.0/8 when it sends its RIPv1 routing updates to R2. R2 summarizes the 10.2.2.0/24 subnet to 10.0.0.0/8 when it sends its RIPv1 routing updates to R1.

To support this topology, R1 and R2 must be configured so that RIPv1 auto-summary is disabled.

R1 sends information about the 10.1.1.0/24 subnet when it sends its RIPv1 routing updates to R2. R2 sends information about the 10.2.2.0/24 subnet when it sends its RIPv1 routing updates to R1. Example of RIPv1 update from R1 to R2:RIP: build update entriesnetwork 10.1.1.0/24 metric 1

Hosts on the 10.1.1.0/24 subnet are unable to communicate with hosts on the 10.2.2.0/24 subnet.

R1 accepts the 10.2.2.0/24 RIPv1 routing updates from R2 and installs the 10.2.2.0/24 route in its routing table. R2 accepts the 10.1.1.0/24 RIPv1 routing updates from R1 and installs the 10.1.1.0/24 route in its routing table.

Answer: A,D

Refer to the exhibit.

Company 1 has merged with Company 2. Company 1 is using RIPv2 as its IGP and Company 2 is using EIGRP as its IGP. EIGRP also is running between R1 and R2 over the WAN link. Which action must be taken to allow these two configurations?

The Company 1 RIP routes appear as external EIGRP routes within Company 2. The Company 2 EIGRP routes appear as RIPv2 routes within Company 1.

Enable RIPv2 on the R2 router.

Enable RIPv2 on the R2 router and on all internal routers of Company 2. Enable EIGRP on all internal routers of Company 1.

Configure mutual route redistribution between RIPv2 and EIGRP on the R1 and R2 routers.

Configure mutual route redistribution between RIPv2 and EIGRP on the R1 router.

Configure mutual route redistribution between RIPv2 and EIGRP on the R2 router.
